I'm using the US Census WMS service describe here. Using code similar to that found in this example, but specifying a data format of "image/svg+xml", I've been able to get the TIGERweb WMS service to give me SVG that is rendered in my map. However, each shape in the SVG just the actual path, with no identifying data.
Is there any way to get TIGERweb to annotate the shapes it serves so I can tell what they are (and process them accordingly with JS, CSS, etc.)? Like, I would like to get an SVG where each path is the boundary of a census block, tract, etc., and where the each path element in the SVG has an attribute giving the block number, FIPS code, or whatever piece of info will allow me to identify what the shape represents.
As it is, I can't see how one could use the TIGERweb SVG data for anything except a plain rendering of the boundaries of counties, tracts, or what have you. Without any identifying information, there's no way to spiff up the shapes with special styling to represent data associated with the census areas.
